All the interfaces are DOWN

[mikado]

Hello,

I’m whole new in VyOS. As I’ve understood the whole configuration of the vyos had to be done using the “configuration” mode.

I’ve done a few tests but all my interfaces are considered as state Up and link Down !

pb_down|690x292

I’ve create two VYos 1.8 on the same adressing plan to make some tests and I think I’ve missed a step. I’ve rechecked the MAC addresses, and they look OK. Is there a reason why my interfaces are still considered as down ?

Thank you for your answer.

can you share your config? Did you assign IP addresses or DHCP to the interfaces?

I’ve difficulties to export the whole configuration considering all my interfaces are dead for the moment. But I’ve added four interfaces on VyOS all configured the same way :

set interfaces ethernet eth0 address ‘192.168.0.19/27’
set interfaces ethernet eth0 duplex ‘auto’
set interfaces ethernet eth0 ipv6 ‘disable-forwarding’
set interfaces ethernet eth0 ipv6 dup-addr-detect-transmits ‘1’
set interfaces ethernet eth0 smp-affinity ‘auto’
set interfaces ethernet eth0 speed ‘auto’
set interfaces ethernet eth0 description ‘Admin’
set interfaces ethernet eth1 duplex ‘auto’
set interfaces ethernet eth1 address ‘192.168.10.25/27’
set interfaces ethernet eth1 ipv6 ‘disable-forwarding’
set interfaces ethernet eth1 ipv6 dup-addr-detect-transmits ‘1’
set interfaces ethernet eth1 smp-affinity ‘auto’
set interfaces ethernet eth1 speed ‘auto’
…
set interfaces ethernet eth3 address ‘192.168.20.19/28’

and added a virtual IP

set interfaces ethernet eth3 vrrp vrrp-group 3 virtual-address ‘192.168.20.110/28’
set interfaces ethernet eth3 vrrp vrrp-group 3 advertise-interval ‘1’
set interfaces ethernet eth3 vrrp vrrp-group 3 preempt ‘true’
set interfaces ethernet eth3 vrrp vrrp-group 3 priority ‘100’
set interfaces ethernet eth3 vrrp vrrp-group 3 ‘rfc3768-compatibility’

You can use serial console even if network is completely down.

The config looks right, so I suppose the issue is elsewhere. What is it running on? Physical hardware or a VM? What does “run show interfaces ethernet ethX physical” show?

[mikado]

It’s a VMWare 6.5 VM

Here is the result of your command for eth0

[mikado]

Ok, I’ve found a solution when I saw that duplex and speed were unknown.

I have a generic Linux 64 bits as VM, so when I added the network interfaces in the VM they were declared with a type “E1000”. However VyOS doesn’t seems to support E1000.

Solution :

• Delete the network interfaces if they are in E1000
• Recreate them in VMXNet 3.

Now the interfaces are seen as UP.

Thank you very much.
